HENRY E. STAGER, OF MILWAUKEE, \VISCONSIN, ASSIGNOR OF ONE-HALF TO JAMES E. WOODWORTH, OF SAME PLACE.

RETURN-BEND FOR STEAM-RADIATORS.

SPECIFICATION forming part of Letters Patent No. 439,907, dated November 4, 1890.

Application filed June 2, 1890. Serial No. 353,968. (No model.)

To all whom it may concern.-

Be it known that I, HENRY E. STAGER, of Milwaukee, in the county of Milwaukee, and in the State of Wisconsin, have invented certain new and useful Improvements in Return- Bends for Steam-Radiators; and I do hereby declare that the following is afull, clear, and exact description thereof.

My invention relates to return-bends for steam-radiators; and it consists in certain peculiarities of construction and combination of parts in connection with the return-bends and valves of said radiators, as will be hereinafter described,with reference to the accompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a vertical longitudinal section taken on line 1 1 of the succeeding figure to illustrate a steam-radiator return-bend and valve constructed according to my invention, and Fig. 2, a vertical transverse section on line 2 2 of the preceding figure.

Referring by letter to the drawings, A represents a shell provided with screw-threaded extensions B C at right angles to each other on opposite sides of atransverse partition D, and screw-threaded or otherwise detachably secured to the outer end of the shell is a cap E, having a projection b for engagement with a wrench.

The partition D is provided with an opening surrounded by a flange c, and the latter forms a seatfor a valve F, that has an arm d pivotally connected to a bracket G, this bracket being detachably connected to the in terior of the shell-section C by means of a screw e, as best illustrated in Fig. 1.

As shown in the drawings, the valve F is held against a collar 9 on an irregular-shaped rod H by means of a set-nut h; but in practice said valve and rod may be otherwise connected, although it is essential that the latter extendin opposite directions from the former.

A float J of soapstone or other suitable material is attached to the inner or irregular shaped portion of the valve-rod H, and is thus brought close to the bottom of the shellA,while on the outer or straight portion of said rod I arrange a counter-Weight K, set-nuts c' being employed to hold said weight in the position to which it may be adjusted.

The shell A above described forms the return-bend for a steam-radiator, the outlet of the latter being coupled to the shell-extension B, and the return-pipe for said radiator likewise connected to the shell-extension C. Now if there is any water or steam pressure back of the partition D in the shell, the float J will rise to overbalance the counter-weight K and open the valve F, the latter swinging on its pivot-connection with the bracket G; but in case of pressure in the return-pipe said valve will be held tight against its seat to prevent flooding of said radiator.

Because of the susceptibility of the floatcontrolled valve the radiator will always drain itself, and said valve being automatic in its action, it does not have to be set at more or less frequent intervals in order to regulate the circulation in said radiator.

As all the working parts of my device are connected to the detachable bracket G, they can be readily withdrawn from the shell A or placedtherein,the capEat the outer end of said shell being removed when such an operation takes place. This is a particular advantage, as it economizes time and labor in finishing the device for the trade and also facilitates the removal of the working parts at any time repairs may be necessary.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A return-bend for steam-radiators, having a transverse partition provided with an opening, a pivoted valve for the opening, a float connected to the valve 011 the inlet side of the partition, and a counterweight also connected to said valve on the outlet side of said partition, substantially as set forth.

2. A return-bend for steam-radiators, that comprises a shell provided with a transverse partition having an opening therein, couplings on opposite sides of the partition, a pivoted valve for the opening in said partition, a rod extended 011 opposite sides of the valve, a float attached to the inner end of the rod, and a counter-weight arranged on the outer end of said rod, substantially as set forth.

3. A return-bend for steam-radiators, that comprises a shell provided with extensions at approximately right angles to each other, a transverse partition arranged in the shell betweenthe extensions thereof and providedwith an opening, a bracket detachably connected In testimony that I claim the foregoing I to to the interior of the vertically-disposed shellhave hereunto set my hand, at Milwaukee, in extension on the outlet side of the partition, the county of Milwaukee and State of Wisa counterweighted float-controlled valve for cousin, in the presence of two Witnesses.

5 the partition-opening, an arm projected from the Valve and pivotally connected to the HENRY E. STAGER. bracket, and a cap detachably fitted to the Witnesses:

outer end of said shell, substantially as set N. E. OLIPHANT,
